OrthoTiN Patient Specific Joint Replacement System
The OrthoTiN TMJ system is designed with focus on matching patient unique anatomy.
The implants geometry is based on the 3D skull model that is generated from the CT Scan of the specific patient.
OrthoTiN Prosthesis are intended to provide a custom bone fitting surface replacements for the joint maintaining maximum bone stock.
The prosthesis are divided into a ramus and fossa component.
Customized surface to match patient specific anatomy (back); standard groove system for UHMWPE bearing surface, custom screw plan for patient
UHMWPE bearing surface, for articulation with titanium condyle.
Advantages of Custom TMJ Design
Model of Facial Skeleton
Contact stress (Unit loading, Von Mises) comparison between spherical (Left) and barrel shaped (Right) condylar head geometries
Custom Ramus Component Allows Fit to Irregular Mandible
Regularly shaped mandible with standard implant (left); irregularly shaped mandible with custom fit implant (right)—custom implant prevents slipping and positions screws correctly
Custom Fossa Component Allows for Exacting Fit
A patient-specific fossa component has the advantage over a standard component in that the implant is in direct contact at each point along the anatomical interface creating stability and reducing micromotion. This also reduces stress within the component by more efficiently transferring joint loads to the bone. In addition, there are certain circumstances in which the patient has anatomical deficits and a standard component cannot be used. All these advantages lead to a more robust and longer-lasting joint replacement solution.
